Cloud & DevOps
Master AWS, Docker, Kubernetes, CI/CD, and infrastructure as code.
At senior levels, "who owns production?" is a signal. Gaps show up as fragile pipelines, opaque outages, and incidents that take too long to diagnose. Interviewers and teams want to see that you understand how deployments and failures propagate—not just that you've run a few Docker commands.
These topics build a rigorous mental model of containers, orchestration, CI/CD, and infra-as-code: where latency and failure surface, where to add observability, and which trade-offs are unavoidable. You'll learn to own the full pipeline and explain your decisions clearly—in interviews and on call.
